#1
Which valve is commonly known as the 'aortic valve'?
Aortic valve
ExplanationControls blood flow from the left ventricle into the aorta.
#2
What is the purpose of the chordae tendineae in heart valves?
Connect the atria and ventricles
ExplanationAnchor the valve flaps and prevent them from prolapsing into the atria.
#3
What is the purpose of the annuloplasty procedure in heart valve surgery?
To reshape and support the valve ring
ExplanationRestores the normal shape and function of the valve's annulus.
#4
What is the primary purpose of the Ross procedure?
Pulmonary valve replacement
ExplanationUsed to replace a defective pulmonary valve with the patient's own aortic valve.
#5
What is the primary function of the mitral valve?
Regulate blood flow from the left atrium to the left ventricle
ExplanationPrevents backward flow of blood from the left ventricle to the left atrium.
#6
Which procedure involves repairing a heart valve without removing it?
Valvuloplasty
ExplanationOpens a narrowed or stiffened heart valve to improve blood flow.
#7
Which condition is characterized by a backward flow of blood through a valve?
Regurgitation
ExplanationBlood leaks backward through a valve when it doesn't close tightly.
#8
During a transcatheter aortic valve replacement (TAVR), where is the new valve typically implanted?
In the aorta
ExplanationThe new valve is inserted through a catheter and placed inside the diseased aortic valve.
#9
What condition does aortic stenosis refer to?
Narrowing of the aortic valve opening
ExplanationReduces the flow of blood from the left ventricle into the aorta.
#10
In a Ross procedure, what is transplanted to replace a defective aortic valve?
Pulmonary valve
ExplanationThe patient's own pulmonary valve is used to replace the diseased aortic valve.
#11
What is the primary risk associated with aortic valve replacement surgery?
Hemorrhage
ExplanationBleeding, both during and after the surgery, is a significant risk.
#12
Which valve procedure is often performed to treat mitral valve prolapse?
Annuloplasty
ExplanationRepairs and reinforces the ring around the valve to prevent leakage.
